Any change to the normal brings with it the need for adaptation, it does not matter whether that change brings lower temperatures (e.g. past and coming glaciations, the 'little ice age', etc.) or higher temperatures (the interglacial temperature rise up to the climatic optimum some ~8500 years ago, the Roman and Viking warm periods, the current warm period). When it gets colder crop yield goes down, crops fail, tree lines go down (as in 'trees fail to thrive on high places') and the productive potential of a given area of land goes down. People will have to move or starve. Many of them will move to lower ground, displacing those who were there already. The displaced will move elsewhere, displacing others. When it gets warmer again the opposite happens, the productive capacity of marginal land will rise while the capacity of land which was already optimal can go down due to drought and subsequent erosion. People will move to this newly productive land, displacing those who were already there. The displaced will move to higher ground or to less productive regions. Another important - and in this case probably the most important - factor is that bad news sells much better than good news. A warmer climate has the potential to make currently suboptimal regions in places like Russia and Canada suitable for productive agriculture. This has happened before - e.g. grapes were grown and wine was probably produced in Denmark during the Viking age [1], the Sahara desert used to be 'covered in vegetation and lakes' [2] - and will happen again. You probably will not hear much in the news about the greening of deserts just like the fact that the planet is a lot 'greener' than it has been in recent history is not published or if it is is put in a bad light like the New York Times 'Global Greening’ Sounds Good. In the Long Run, It’s Terrible. [3] put it. [1] https://videnskab.dk/kultur-samfund/foerste-bevis-vikinger-kan-have-dyrket-vin/ https://videnskab.dk/kultur-samfund/foerste-bevis-vikinger-k...
